The two parts that make it hard to believe Oswald acted alone:

This is the view from the TSBD window for that fatal 3rd shot according to the ABC special JFK Beyond Conspiracy computer generated simulation. The red spot is where it hit.
This is the computer generated view from the grassy noll when the last shot was fired. No way it came from the picket fence area. Again the red spot is where it actually hit. The bullet would of most likely hit Mrs Kennedy or the car if this was where the fatal shot was fired from.
